Kinetic Sculpture Controller Science education in the Unites States is lagging behind many countries, and is critical for an informed and productive public. One response has been to increase interest and enthusiasm for science through hands-on robot type projects (e.g. Lego league and FIRST robotics). Another response has been an increased emphasis on meeting state curriculum objectives and standardized testing. However, these two approaches are often seen as incompatible, since preparation for standardized testing leaves little time for the exploration and creativity associated with hands-on projects. The end result is that the hands-on projects are typically relegated to after school clubs where only a small percentage of students participate. The objective of this project is to create a hands-on educational module that will combine elements of the hands-on approach while still meeting curriculum objectives. We will use a Kinetic Sculpture to teach fundamental concepts of physics including conservation of energy, trajectories, impacts, and more. The approach has been used for the past 3 years by the project sponsors during a summer course offered at UCSD for high school students. We have created optical motion sensors that measure ball speed on the kinetic sculpture, and a controller that can move elements of the kinetic sculpture. This allows students to create their own sculpture and explore physics in a creative and interactive fashion. Figure of sculpture, link ot video, and controller) While the summer course has been very popular with the students, we wish to make this kit available to teachers around the country. The kit developed at UCSD has a custom controller, which works well but would be expensive to market nationwide. In the past few years, controllers and dataloggers have been developed for K-12 education from Verneir, Pasco, and Lego. We would like to use these off-the-shelf controllers, since many high schools already own them and teachers are familiar with how to work with them. In, order to implement the kinetic sculptures with existing controllers we will need to develop a ball speed sensor that will interface to any of these existing controllers. The project will involve: Development of an optical ball speed sensor Integration of a microprocessor for precise timing and electronic integration Development of an aesthetic housing that will be made using 3D rapid prototyping, and designed for larger scale injected molded plastic design. The project will involve technical work as well as consulting with a high school teacher. Skills: Sensor development, electronics, 3D rapid prototyping, and product design.
